Step-by-step explanation:

Answer:

m - 4m = 2m

-4 = 2m -m

- 2 = m

Answer:

m = -4

Step-by-step explanation:

Add 4 to both sides of the equation

Simplify

Add the numbers

= 2 + 4

Subtract 2 from both sides of the equation

=2+4

−2=2+4−2

Simplify

Divide both sides of the equation by the same term

Simplify

Answer:

Answer:

3/4 feet

Step-by-step explanation:

the common denominator (4) always stays the same.

you add the 3 pieces.

Answer:

Step-by-step explanation:

(x₁ , y₁) = (6, -4)  &    (x₂ , y₂) =(-1 , -4)

In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.

Slope of line parallel to x-axis = 0

Answer:

m∠8 = 49°

Step-by-step explanation:

∠7 and ∠8 are same-side interior angles.

Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.

Let's use the variable 'x' to represent the unknown measure of angle ∠8.

[tex]131 +x=180[/tex]

[tex]131-131=0[/tex] (cancels itself out)

[tex]180-131=49[/tex]

[tex]x=49[/tex]

Therefore, the measure of ∠8 is 49°.

Answer:

10,010,011,001

Step-by-step explanation:

Converting the number 10010011001 into a number with commas gives us 10,010,011,001.

Given that,

The number is 10010011001.

Used the concpet of number system which states that,

A writing system used to express numbers is known as a number system. It is the mathematical notation used to consistently express the numbers in a particular set using digits or other symbols.

Here, the number is 10010011001.

So, it can be written as,

10010011001 = 10,010,011,001

Therefore, the number 10010011001 with commas would be 10,010,011,001.

The line is:

Answer:

b = 1

Step-by-step explanation:

We know that

y = mx + b

-3 = -4/5 × 5 + b

-3 = -20/5 + b

-3 = -4 + b

-3 + 4 = b

1 = b

Answer:

The fourth option is the answer.

Step-by-step explanation:

Use distance formula

[tex] {x}^{2} + {y}^{2} = {d}^{2} [/tex]

where x is the distance between the two endpoints of the congruent line segment and y is the distance between the congruent line segment.

[tex] {3}^{2} + {6}^{2} = 45[/tex]

Set 45 equal to d^2.

[tex]45 = {d}^{2} [/tex]

[tex] \sqrt{45} = d[/tex]

[tex]3 \sqrt{5} = d[/tex]

L and M have the same distance between points as well. so they are congruent.

In geometry, transformations are used to move points from one position to another.

The preimage is given as:

[tex]S =(-3,4)[/tex]

[tex]T = (3,4)[/tex]

[tex]U = (-1,0)[/tex]

The image is given as:

[tex]S' = (-2,2)[/tex]

[tex]T' =(4,2)[/tex]

[tex]U' = (0,-2)[/tex]

Using points S and S' as our reference point, we have:

[tex]S =(-3,4)[/tex] and [tex]S' = (-2,2)[/tex]

Calculate transformation

[tex](x,y) \to S -S'[/tex]

[tex](x,y) \to (-2,2)-(-3,4)[/tex]

Rewrite as:

[tex](x,y) \to (-2--3,2-4)[/tex]

[tex](x,y) \to (-2+3,2-4)[/tex]

[tex](x,y) \to (1,-2)[/tex]

So, the transformation from the preimage to image is:

[tex](x,y) \to (x + 1, y-2)[/tex]

Calculate the lengths of the sides of the preimage and the image

Using the following distance formula, we have:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]ST = \sqrt{(-3 - 3)^2 + (4 - 4)^2} = 6[/tex]

[tex]SU = \sqrt{(-3 - -1)^2 + (4 - 0)^2} = \sqrt{20[/tex]

[tex]TU = \sqrt{(3 - -1)^2 + (4 - 0)^2} = \sqrt{32[/tex]

and

[tex]S'T' = \sqrt{(-2 - 4)^2 + (2 - 2)^2} = 6[/tex]

[tex]S'U' = \sqrt{(-2 - 0)^2 + (2 -- 2)^2} = \sqrt{20[/tex]

[tex]T'U' = \sqrt{(4 -0)^2 + (2 -- 2)^2} = \sqrt{32[/tex]

Since

[tex]ST = S'T'= 6[/tex]

[tex]SU = S'U'= \sqrt{20[/tex]

and

[tex]TU = T'U'= \sqrt{32[/tex]

Then, the transformation preserves length

From the graph of [tex]\triangle STU[/tex] and [tex]\triangle S'T'U'[/tex]

Since

[tex]\angle S = \angle S' = 76^o[/tex]

[tex]\angle T = \angle T' = 45^o[/tex]

[tex]\angle U = \angle U' = 59^o[/tex]

Then, the transformation preserves angle measure.

Answer:

h(x) = 3x - 2

Step-by-step explanation:

The opposite of division is multiplying and the opposite of addition is Subtraction.

Answer:i i am going to go with h(x)=1/3 x+2

Step-by-step explanation:

Answer:

h=39/4

Step-by-step explanation:

area of a triangle = 1/2(b*h)

base = 8 inches

area =39 square inches

input the values given:

39=1/2(8*h)

multiply the right side by 1/2

39=(1/2)8h

find half of 8

39=1/2*8 (h)

hence,

39=4h

divide both sides by 4

hence,

39/4=h

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x
